IMPROVEMENT IN LUBRIGATORS.

Beit known that I,`JAMES RICHEY, of Cincinnati, Hamilton county, Ohio, have invented' a new and useful Lubricator; and I hereby declare the following to be afnll, clear,- and Iexactdescription thereof, reference being had tothe accompanying drawings, mak-ing part of this specification.

My invention relates to that class of devices'which are employedfor the lubrication of journal-hearngs,`

lSte.; andthe rst part of my improvement consists 4in forming the oil-reservoir, and the stem by which the lubricator is attached to the journal-bo1r, of a single piece of metal, .thereby-'producing a perfectly reliable and air-tight article.- v j Thesecond partof my improvementslconsists in providing the-oilreservoir with glass or'other transparent windows, by which means the amount of .oil in said reservoircan be seen at a glance.

Thethird part of my improvement relates to a. sediment-chamber, which is located at the bottomof the oilreservoir, for the purpose of collecting any impurities that may be precipitated from the'oil. In theaccompanyling'drawingsl Figure 1 is an axial section of a lubricator embodying my improvements, a. portion ofthe stembeing shown in elevation, `to exhibit its external screw-thread.

Figure 2 is'a horizontal section of the same, taken at the line :c zt.

My lubricator consists essentially of an oil -reservoir, A, and stem B, which are formed `of a. single piece of` Britannia or any otherpeasily-iusib'le metal. The sides ofthe reservoir' arefurnished with glass or other transparent windows, C Cfthe windows boing secured to therreservoir by pre-heating and casting the material of the latter aboutthem.

The openings in `which the windows are inserted are provided with outwardly-projecting ridges a a', which notronly stilen the oil-,reservor, but also serve to protect thowindows from injury.

The upper part of the reservoir is provided with a screw-threadedvcap, D which,being removed, allowsthe I reservoir to be filled.

The stem B projects upwardly a slight dist-ance Yfrom the bottom of the oilgreservoir, as shown at 6, so as to forma sediment-chamber, E, between said projection and the sides and bottom of the reservoir. v The interior of the stem B is provided with a. longitudinal channel, F, down which the oil flows from the chamber to the shaft which is to be lubricated, and the outside of the stem is screw-threaded at f, so as Vto 'l permit of the apparatus-being secured to the journal-box. j

'lheoil-reservoir and stem being formed of a single piece of metal, obviates the necessity of ajoint'between them,:whieh must always be the case when these two members are madeof separate pieces, and it will vbe seen thatlby omitting said joint I dispense witha very objectionable feature peculiar to all of the lubricators which `have been constructed, it being well linwn that a, leak between the stemfand reservoir'will impair ifnot entirely destroy .the 'etlicicncy of these devices. I

The provision of the windows- C C enables the attendant to observev the stage. of oil in the reservoir, so

that he can replenish it before it becomes entirely empty. The stem B being prolonged at b so as to project'` above the bottom of the reservoir, prevents the channel F boing clogged up by anyilnpuritiescontained in theV oil, as thescwill collect in the sediment-chamber, from which they can be readily remove'dfas occasionrequires.y

I claim hereinasnew and of my invention- A lubricator, with its oil-reservoir cast-in one piece with the stein B, and furnished with windows C C',

all substantially in the manner herein described and for the-purposes specified.

In testimony of whi'hh invention, Ihereunto set my hand. i

JAMES RIoHEY.
